Abstract: | The transit of exoplanets across a stellar disk will often occur in GAIA observations. A safe detection of the slight dimming
of the star can be made many hundred times, i.e. in cases where the star is sufficiently constant in intensity, and the photometry
is very precise. When combined with the simultaneous GAIA astrometry or ground-based radial velocities the scientific harvest
is orbit, mass and mass density for hundreds of exoplanets. We have typically considered Jupiter-size planets at Earth-like
distances from the stars.
